I have few medium traffic traffic sites which i have been running for about a year. I did lots of link building work by submitting to directories which are free of charge.
I did a check with future prediction of pagerank and tools like iwebtool shows i will be getting PR5 in the future. No matter how hard i try, the maximum attainable page rank seems to be PR5. My question is what exactly need to be done to push that page rank to PR6 or more...
Has any one done that before...
